As ações de sentar e levantar do solo são influenciadas por variáveis morfo-funcionais ; Sitting and rising from the floor are influenced by morphologic and functional variables

We aim to study the influence of morphologic and functional variables on the actions of sitting and rising from the floor, as assessed by the Sitting-Rising Test (SRT). Randomly, in the 160 physically active policemen, we selected 42, from those who achieved the maximal score in both actions of the SRT and 49, from the others. The age ranged from 18 to 45 years (74 ± 10 kg and 176 ± 7 cm [mean ± sd]). We also evaluated or calculated: abdominal girth (AG), sum of six skinfolds (6sf Z), body fat percentage (BF%), BMI, superior to inferior skinfolds ratio (SISR), specific and general flexibility in 11 movements (Flexitest), maximun standing long jump distance (MSLJD) and balance (Romberg test). Factor analysis did not identify the presence of sitting and rising performance in any of the four factors that explained 69% of the total sample variance. Multiple regression verified an association between sitting and SLJD, BMI, AG and ankle flexibility, and between rising and SLJD, AG, age and general flexibility (p < 0.01). The canonical analysis showed that the performances in the actions, when evaluated together, provide a stronger association with age, BMI, SISR, SF Z, AG, SLJD, and with ankle, knee, hip and trunk flexibility (rc = 0.63, p < 0.01). We conclude that the SRT can provide simple indicators of functional fitness in adults ; Objetivamos estudar a influência de variáveis morfo-funcionais nas ações de sentar e levantar do solo, avaliadas pelo Teste Sentar-Levantar (TSL). Randomicamente, em 160 policiais fisicamente ativos, selecionamos 42, dentre os que alcançaram escore máximo nas ações do TSL, e 49, dentre os demais. A idade variou entre 18 a 45 anos (74 ± 10 kg e 176 ± 7 cm [média ± dp]). Foram medidos ou calculados: circunferência abdominal (CA), somatória de seis dobras cutâneas (X 6dc), percentual de gordura (% g), IMC, relação entre dobras cutâneas superiores e inferiores (RDCSI), flexibilidade específica e geral em 11 movimentos (Flexiteste), distância em salto horizontal máximo (DSHM) e ...
